Feature Request: @task metadata

OSS Product Help LangGraph
1

We pass custom execution options to our nodes with the graph.add_node(metadata=…)field provided by the Graph API. We’re also interested in using the Functional API and would like to request the addition of a@task(metadata=….) field for tasks.

Without this fix, we need to pass a dictionary of custom execution options, and look up tasks by name, which looks something like the following:

{
    "task-1": {
        "option-1": 1,
        "option-2": 2,
    },
    ...
}

We’ve already made and tested this change on our fork and have validated it in our codebase. Let me know if I have permission to open a PR. Thank you!
